Calculate the low and high watermarks based on the low and high
clocks for the current power state. The dynamic pm hw will select
the appropriate watermark based on the internal dpm state.

Newer asics don't have specific UVD states.
Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

Newer asics have a lot of vram so it's less of an
issue to waste a little more space for the gart
page table. This gives us some additional gart space
before having to migrate to non-gart system ram
for games, etc. where we use up most of vram.

1. Handle the the thermal state directly in the work handler.
Remove the state selection function since nothing else uses it now.
2. On some asics there is no thermal state, so we just use a regular
state and force the low performance state.

Use the UVD handle information to determine which
which power states to select when using UVD. For
example, decoding a single SD stream requires much
lower clocks than multiple HD streams.
v2: switch to a cleaner dpm/uvd interface
v3: change the uvd power state while streams
are active if need be

Fix the typo introduced in
commit 1a2eb4604b85c5efb343da8a4dcf41288fcfca85

drm/i915: Hook up Ivybridge eDP
This fixes eDP link-training failures and cases where all voltage swing
/pre-emphasis levels were tried and failed during clock recovery and -
as a fallback - we go on to do channel equalization with the last voltage
swing/pre-emphasis level which will succeed. Both issues can lead to a
blank screen.

That was how it was designed and all the callers expect it.

Commit dcd7b8bd63cb81c5b973bf86510ca3c80bbbd162 ("staging: comedi: put
module _after_ detach" by myself) reversed a couple of calls in
`comedi_device_attach()` when recovering from an error returned by the
low-level driver's 'attach' handler. Unfortunately, that introduced a
NULL pointer dereference bug as `dev->driver` is NULL after the call to
`comedi_device_detach()`. We still have a pointer to the low-level
comedi driver structure in the `driv` variable, so use that instead.

error detection
Fix the issue with improper counting number of flying bio requests for
BIO_EOPNOTSUPP error detection case.
The sb_nbio must be incremented exactly the same number of times as
complete() function was called (or will be called) because
nilfs_segbuf_wait() will call wail_for_completion() for the number of
times set to sb_nbio:
do {
wait_for_completion(&segbuf->sb_bio_event);
} while (--segbuf->sb_nbio > 0);
Two functions complete() and wait_for_completion() must be called the
same number of times for the same sb_bio_event. Otherwise,
wait_for_completion() will hang or leak.

Being a low-level component, various drivers (e.g. olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe. Therefore the OLPC EC driver must be initialised before other
drivers try to use it. This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").
Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.
Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC. The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

IP sends device configuration (see inet_fill_link_af) as an array

exposed to userspace through any current santized header file.
It was available back in 2.6.32 (in /usr/include/linux/sysctl.h)
but was broken by:

ipv4: AF_INET link address family
Putting them in /usr/include/linux/ip.h seemed the logical match
for the DEVCONF_ definitions for IPV6 in /usr/include/linux/ip6.h

rfc 4861 says the Redirected Header option is optional, so
the kernel should not drop the Redirect Message that has no
Redirected Header option. In this patch, the function
ip6_redirect_no_header() is introduced to deal with that
condition.

commit fba875591 ("disable TX in be_close()") disabled TX in be_close()
to protect be_xmit() from touching freed up queues in the AER recovery
flow. But, TX must be disabled *before* cleaning up TX completions in
the close() path, not after. This allows be_tx_compl_clean() to free up
all TX-req skbs that were notified to the HW.

This reverts commit 58ad436fcf49810aa006016107f494c9ac9013db.
It turns out that the change introduced a potential deadlock
by causing a locking dependency with netlink's cb_mutex. I
can't seem to find a way to resolve this without doing major
changes to the locking, so revert this.
